Make array follow taurus knot
The process is rather simple. First take your torus knot, select one edge loop and press P to separate by selection. Then you are left with 2 objects - the Knot and the &quot;loop&quot;

Then, you can delete the knot, leaving only the edge loop (if that's what you want). Select the loop and convert it to a curve.

Then, add the mesh you want to repeat along the curve and give it an Array Modifier and a Curve modifier.  Make sure the curve is the second in the list. For the curve object, select the &quot;curve&quot; you made from the edge loop.

As usual, you can rotate/transform the &quot;following mesh&quot; (in edit mode) to give different effects.
